A sentimental yearning for some happy time from the past is what we call nostalgia.

There’s a lot of money in nostalgia.

Which brings us to Disney’s live-action remakes.

Every terrific Disney animated movie that thrilled you during childhood is coming back as a new film with people, not drawings.

In 3D.

You will smile fondly as you are separated from your money.

This Friday, Beauty and the Beast is back on the big screen, with Emma Watson as the bookish Belle and Dan Stevens as the prince punished for his pride with a beastly spell.

Unless he falls in love, the prince will remain a beast and never regain his human form. Enter Belle, who fearlessly and selflessly agrees to stay at the beast’s castle. In time, she tames him, uncovers his better nature, gets him to shower regularly, dress better and pay more than $12 for a haircut and becomes his salvation.

So, yeah — pretty much the same old love story, but with a cast that includes Luke Evans, Josh Gad and Kevin Kline, and, as the magical castle furniture, Ewan McGregor, Ian McKellen, Emma Thompson, Audra McDonald and Stanley Tucci.

Many young men, loudly protesting that they would rather see Logan, will secretly be glad to go with their girlfriends (or boyfriends) to see Beauty and the Beast because the animated version thrilled them to bits when they were four years old. KILL THE BEAST!!!

A lot of millennials saw the animated Beauty and the Beast as kids, just as they saw The Little Mermaid, Aladdin, The Lion King and Mulan during the ‘90s period known as Disney’s Renaissance.

All those films are getting a live-action reboot.

(Well, all except Pocahontas and The Hunchback of Notre Dame, apparently.)

Disney has already given Cinderella, Alice in Wonderland, Maleficent and The Jungle Book the live-action treatment. As they continue to recycle known winners at the box office, here’s what else you can expect:

MULAN

November 2018

A live-action Mulan is coming to theatres just as soon as Disney can find a Chinese actress (hint: not Scarlett Johansson) to star in the picture.

The story concerns a brave young woman who eschews traditional subservient female roles. She disguises herself as a man to save her father, taking his place in the army and becoming a hero. Niki Caro (North Country; The Zookeeper’s Wife) will direct.

THE LITTLE MERMAID

No release date

Lin-Manuel Miranda (Hamilton) is all over Disney’s Moana, will appear with Emily Blunt in Mary Poppins Returns and has told Vulture he’s working on some top secret animated movie with Zootopia’s co-director Byron Howard. Miranda is also working with original Little Mermaid composer Alan Menken on songs for the new, live action Little Mermaid movie.

There seem to be several upcoming movie versions of the story, which involves a mermaid giving up her fishtailed, underwater status to save the human man she loves.

THE LION KING

No release date

The Lion King has already been spun into a hit Broadway show and will become a ‘live-action’ picture with Donald Glover as the voice of Simba and James Earl Jones as the voice of Mufasa — the same role he had in the 1994 animated version. One assumes the animals will be a mix of live and CGI.

Jon Favreau, who helmed last year’s live-action version of The Jungle Book, will direct.

Which reminds us …

THE JUNGLE BOOK 2

No release date

According to the Hollywood Reporter, Jon Favreau will direct a live-action sequel to his Oscar-winning 2016 hit. And speaking of sequels …

MALEFICENT 2

No release date

Angelina Jolie is already on board for this second chapter in the origin story of the bad fairy in Sleeping Beauty. Linda Woolverton, who wrote Maleficent (as well as umpteen other Disney projects) is writing the screenplay.

DUMBO

No release date

Tim Burton is set to direct this live-action remake, which will present both real and CGI elephants. Dumbo is a baby elephant mercilessly teased for his big ears, but who is eventually triumphant in his circus performances. Tom Hanks is said to be in talks to play the villain. No doubt the new Dumbo will eradicate the racial stereotypes that are a part of the animated movie. On that note, don’t hold your breath for a live-action version of Song of the South.

ALADDIN

No release date

Guy Ritchie will direct this tale, set in the Middle East, about an Arab street urchin who takes the overprotected Princess Jasmine along on a flying carpet adventure. Casting should be interesting in what is essentially an action movie. But who can replace Robin Williams (voice) as the genie?

PETER PAN

2018

Peter Pan started life as a play and a novel and has already been a live-action movie and a Broadway production umpteen times. By now, the boy who doesn’t want to grow up is familiar to just about everybody. David Lowery, who directed last year’s Pete’s Dragon remake, helms this new version.

TINK or TINKER BELL

No release date

That’s right — Peter Pan’s little fairy friend is getting her own movie, and Reese Witherspoon is attached. This is not the only spinoff or origin tale coming up, either:

GENIES

No release date

This Aladdin prequel will show viewers just how a genie gets trapped in a lamp in the first place.

CRUELLA

2018

Glenn Close crushed as Cruella in the live-action version of 101 Dalmatians; Emma Stone takes over the role for this Cruella de Vil origin story. Alex Timbers (Mozart in the Jungle) will direct. At long last, we will all discover the reasons for Cruella’s taste in puppy fur clothing. Gross.

PRINCE CHARMING

No release date

One interchangeable prince or another from all those Disney animated tales is going to get his own origin story in this live-action update.

PINOCCHIO

No release date

Don’t confuse Disney’s live-action remake with all the other movie versions of the little-wooden-puppet-who-wants-to-be-a real-boy that are scheduled. There’s a scary version, an Italian version and a Robert Downey Jr. as Mister Geppetto version. Accept no substitutes.

SNOW WHITE

No release date

Back in December, Variety announced that Disney would be making a live-action remake of Snow White, and it will be a musical. The 1937 fairy tale classic will get more songs from Benj Pasek and Justin Paul (La La Land) who are working on the new musical numbers.

ROSE RED

No release date

The live-action Snow White companion movie will focus on her sister, Rose Red. After Snow White bites the poison apple, Rose Red has to rescue her with the help of the dwarves. The Hollywood Reporter says Evan Daugherty is involved; he wrote Snow White and the Huntsman, a film that sparked an outcry following the casting of regular sized actors such as Bob Hoskins and Ray Winstone as dwarfs. A similar bit of digital shrinking created the little people in The Hobbit, too. Uh, oh.

WINNIE THE POOH

No release date

This live-action reimagining, according to moviepilot, will feature an adult Christopher Robin revisiting the Hundred Acre Wood. Alex Perry is the writer here.

THE SWORD IN THE STONE

No release date

Yes, even this King Arthur tale will get the live-action treatment, and THR says Game of Thrones writer Bryan Cogman will write the screenplay. The story centres on Arthur’s childhood and his adventures with Merlin; Disney had better hurry up and secure Jacob Tremblay before the kid has a growth spurt.
